Review on ROTTO Bike Top Tube Bag: Secure Bicycle Phone Holder with Touchscreen Function and Rain Cover by Mike Cody

Conceptually if you look at the description of this product you really want it and for less than $20 why not. This bag can suit you very well for many reasons, such as all the features it has, but here's why you might want to spend your $20 on something else. If you sit in your seat 100% of the time, you could use this bag. On the other hand, if you ever get up and jump out of the saddle. Forget it. It's wide enough for a phone, so on the bike you can spread your knees a bit to fit in your bag (assuming you're comfortable), but if you get up and rock the bike from side to side, the sack rattles above the knees and up to mid-thighs. They will actually get tangled in the pocket, and that's NOT a good thing. To get it home on my first ride I had to take it off and tie it to the stem to get it out of the way. Lots of stuff right on the bag that other reviewers have mentioned, like the rather unique velcro straps. But other things not so much. It was technically possible to use a touchscreen through plastic, but with a very low success rate. Unless you're alone on a country road, you spend too much time looking down trying to tinker with it and end up in an accident. If your phone is like most others, the power button is on the side of the phone and you use it to turn on the display. Well, those buttons are almost impossible to push through the side panel of the bag. So if you're sedentary all the time, have a longer mountain bike frame and only want to be able to access your phone during a break, this is probably the best option in this price range.
